AUTOMATIC VENDING-MACHINE.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed March 25, 1905. Serial No. 262,004.

To all whom it may concern.-

Be it known that I, GEORGE C. YooUM, a citizen of the United States,residing at Scranton, in the county of Lackawanna-and State ofPennsylvania, have invented certain new and useful Improvements inAutomatic Vending-Machines, of which the following is a specification.

My present invention relates to machines for automatically cutting offand delivering checks from paper strips. The machine is intendedprincipally for delivering checks such as are commonly used inconnection With soda-Water fountains. It is customary at present for thepurchaser. to obtain a ticket or check from one clerk and to hand it tothe clerk dispensing the beverages in payment for a drink. The purposeof this custom is to save the clerk at the soda-water fountain, whosehands are usually wet or moist, the trouble of handling money, also toserve as a check upon the honesty of the clerk. By means of my imrovements the services of the clerk who so ls the checks may bedispensed with, as the machine will automatically cut ofl and deliver acheck to the purchaser Whenever the latter inserts a coin of the re erdenomination in the machine.

The details and o eration of my invention will be clear from thefollowing description, taken in connection with the accompanyingdrawings.

In the accompanying drawings, which illustrate'my invention, I haveshown the mechanism inclosed in a suitable casing, the latter beingshown in section in some of the views.

In the drawings, Figure 1 is a plan view of the machine, the casingbeing shown in horizontal section. Fig. 1 is a side View of the machine,on a small scale, showing the motor belted thereto. Fig. 2 is a sideview of the mechanism, partly broken away, the parts being shown intheir normal positions in full lines and the positions of the coin-leverand tappet-levcr at the time when a coin first enters the coin-loverbeing indicated in dotted lines and the casing being shown in verticalsection. Fig. 3 is a similar View showing the position of the partswhile the belt is running on the tight pulley and illustrating theoperation of moving the belt-shifting devices to carry the belt onto theloose pulley. Fig. 4 is a side viewof the mechanism, taken from theopposite side of the machine from that shown in Figs. 2 and 3, thecasing being shown in vertical section and the tappet-le- 'shifted backonto the loose ver being shown in full lines the ositionwhich it assumeswhen a coin is firstinserted in the coin-lever and in dotted lines inthe position which it assumes at the time the belt-shifting devices areunlocked-or released to permit the belt to shift onto the ti ht pulley.Fig. 5 is a rear view of the mec anism. Fig. 6 is a section on the line6 6 of Fig. 2. Figs. 7 and 8 are detailsectional views showing thelocking device for the belt-shifter in two positions.- Fig. 9 is adetail view show ing the coin-lever tilted by a coin and thetripping-pin on the tight pulley engaging the coin-retaining device; andFig. 10 is an end -view of the coin-lever, illustrating the movements ofthe coin-retainer.

Referring to the drawings, A indicates a suitable casing within whichthemachin'e is inclosed, and-B, Fig. 1, indicates a suitable motor whichruns continually while the machine is in service and operates-themechanism by means of a belt (I. This belt C normally runs upon a loosepulley 1, which turns upon a main driving or operating shaft 2 and isshifted automatically each time a coin is inserted into the machine ontoa pulley 3, which is fixed to the operating-shaft 2. The rotation of theoperating-shaft causes the feeding and cutting mechanism to deliver oneticket, and the belt is automatically time the ticket is delivered. hemanner of efi'ecting'the movement of the belt will be hereinafterdescribed. The tickets are ar ranged in .the form of a paper-roll D,which is suitably supported within a reel 4, journaled upon a pair ofstandards 5 in the rear of the casing. The paper strip (1 extends fromthe roll between a air of feed-wheels 6 and a roller'i, arranger beneaththefeed-Wheels. A spring-brake 8 bears lightly against the paper-rolland prevents the strip of paper from becoming loose within the machine.These feed-wheels are turned in the direction indicated by the arrow,Fig. 4, each time the op erating-shaft 2 is turned by means of a crank9, securcd to said shaft and connected by a link 10 to a rocker-arm 11,which is journaled upon a post 12 and connected to one end of a link 13,the other end of said link being connected to a clutch-lever 14. Theclutchle ver 14 is connected to a clutch-head 15, Figs. 1, 4, 5, and 6,which is journaled upon an extension of the shaft 6, which supports thefeed-rollers. The clutch-head 15 has teeth, as shown, which in onedirection of moveulley by the ment engage teeth upon the disk 16, whichis secured to the shaft 6, and in the opposite direction the teeth ofthe clutchhead slip over the teeth on said disk. It will be seen fromthe arrangement of links and levers between the operating-shaft and theclutch-head that the arm 14 will oscillate forward and then.

backward each time the operating-shaft makes a complete revolution.Durin the forward movement of the arm 14 the c utch will cause thefeed-wheels to turn and feed forward a length of paper equal to oneticket. On the backward movement of the arm 14 the feed-wheels willremain stationary, as the teeth of the clutch-head will slip over theteeth on the disk attached to the feed-wheel shaft andlwill be heldagainst any backward movement by a pawl 17 engaging teeth 18 upon thedisk. The paper 'WhlCh is fed forward by the feed-wheels rests upon achute consisting of two separately-Sn ported sections 19 and 19",leading to a sibt 20 in the casing, through which the ticket isdelivered when out off. After the feed movement has ceased a rotaryknife or cutter 21 shears the paper transversely adjacent to the end ofthe part 19 of the paper rest or chute. This cutter makes one completerevolution for each movement of. the operating-shaft 2. As

bine bevel and spur pinion 26,

' and mounte shown, the cutter is mounted upon a shaft 22, extendinparallel with the paper-support d in suitable bearings in the machine;The shaft 22 may be geared directly to the shaft 2; but in the drawingsthe cuttershaft is geared to the operating-shaft by .means of a trainof. gearing proportioned to make the shafts turn in unison. As shown, abevel-pinion 23 upon the cutter-shaft engages bevel-teeth upon acombined spur and bevel pinion 24, and a bevel-pinion 25 upon the oerating-shaft 2 engages a similar com suitably j ournaled beneath saidlatter shaft; The spurteeth upon the pinions 24 and 26 each mesh with aspur-gear 27, b means of which motion is communicated rom one set of'inions to the other and from the operating-s aft to the cutter-shaft.The normal osition of the knife or cutter isshown in full ines in Fig.v6, and the position of the cutter when it first enga es the paper isindicated in dotted lines.

rom t e foregoing description it Will be apparent that each revolutionof the operating-shaft 2 will cause the paper to be fed forward thelength of one ticketand the cutter is arranged to sever the 'pape'rimmediately afterthe feeding movementhas stopped, the

cutter making one revolution for each revolution of the operating-shaft.

The loose pulley 1 is constantly driven in the direction indicated bythe arrow, and a pinion 28 is secured'to and rotates with the oosepulley upon the shaft2. This pinion engages a large spur-gear 29, whichis j ournaled upon a suitable standard 30 and has at one side of its rima tappet 31 for a purpose to be hereinafter described. Normally theloose pulley, the gear 29, and the pinion 28 are driven continuously,the remaining parts of the machine being stationary until a coin isinserted into the machine. of rotationof the loose pulley and the cam ortappet-gear 29 are indicated by the arrows in the several figures of thedrawings.

The belt C passes between the arms 32 of a belt-shifting lever 33, whichis pivotally secured to the base of the machine by a pivotscrew 34. Thebelt-shifter swings in a horizontal'plane for a sufficient distance toshift the belt from the loose pulley onto the tight pulley. A slidingrod 35 is pivotally connected to the belt-shifter, and this rod isprovided with a shoulder 36. A spring 37 constantly tends to draw thebelt-shifter into position to move the belt onto the tight pulley; butthe belt-shifter is normally held in The direction position with thebelt running on the loose suitable bearing 39 and carries anupwardlyextending bracket 40. Upon the hub of the tight pulley isarranged a pin or detent 41, which normally rests upon the top of thebracket 40 when the latter is in its normal position. (Shown in Fig. 2.)A spring-finger 42, secured to the bracket 40, extends over the pin 41in the normal position of the parts, and it will be seen that the tightpulley is normally locked between the finger 42 and, the upper end ofthe bracket 40. When the slide 35 and post 40 are'moved by the spring 37into tight pu ley by the release of the detent 38, it will be seen thatthe looking or detent pin 41 will be disengaged from the bracket 40. InFig. 3 the bracket is shown in full lines in its normal position and indotted lines moved rearwardly. The bracket 40 is also provided with ashoulder or cam-surface 43, arranged so that it will be in the path ofthe in 41 when the bracket 40 is moved rearwar ly, as shown in Fig. 3,and it will be seen that after the belt-shifter has moved into positionto direct the belt onto the tight ulley and the pin 41 has been releasedfrom the bracket40, the tight pulley will rotate, bringing the pin 41against the cam or shoulder 43, and the continued m vement of the tightpulley will return the bracket 40 to its normal position. The detent 38then drops behind the shoulder 36 and holds the slid e-rod, bracket, andbeltshifter in the normal position during the remainder of therevolution of the tight pulley,

osition to throw the belt onto the be delivered and cut off.

The detent or locking device 38 is released each time a coin is insertedin the machine by the following mechanism: The detent is arranged toslide vertically in a suitable bracket 44 and is normally presseddownward by a spring 45. A pin 46, secured to the detent, extendsthrough a vertical slot 47 in a vertically-movable rod 48, (see Figs. 7

and 8,) having its upper end pivoted to the shorter or lighter end of acounterbalanced lever 49, which is pivoted upon a suitable standard 50.A link 51 is connected to the longer or weighted arm of saidcounterbalanced lever and to one end of a tappet-lever 52. The cam ortappet-lever 52 is pivoted upon a suitable support 53, and its free endis movable into position to be engaged by the cam or tappet 31 upon thewheel 29, as indicated in dotted lines in Fig. 2 and in full lines inFig. 4. Normally the cam or tappet-lever is held with its free end outof the ath of movement of the tappet, as indicate( in full lines, Fig.31, by means of a coin-lever 54, which is pivoted upon a suitablesupport 55 and which has a weighted end normally resting upon thelighter or shorter arm of the counterbalanced lever 49. As shown,'thelever 54 has a weight 54 at one end and a coin-receptacle56 at itsopposite end, said receptacle being arranged in line with a coinchute58. As long as the weighted arm of the coin-lever 54 rests upon the freeend of the lever 49 the tappet-lever 52 will be held Whenever a coin isinserted through the coin-chute into out of the path of the tappet.

the coin-receptacle 56, the coin-lever 54 tilts under the weight of thecoin, and the counterbalanced lever 49 is thereby ermitted to rock,causing the depression of t e rear end of the tappet-lever and theelevation of its forward end into the ath of the tappet 31, as indicatedin dotted lines in Figs. 2 and 5. The tappet-lever is temporarily heldin its position bythe pin 46 upon the detent 38, which forms a stop tolimit the upward movement of the rod 48 so long as the latter is onlactuated by the weight of the counterba anced lever 49.

As the cam or tappet-wheel 29 is constantly rotated the tappet 31 willengage the free end of the ta pet-lever 52 soon after the latter isallowe to assume the position shown in dotted lines, Fig. 2, by theinsertion of a coin into the machine. When the tappet engages thetappet-lever, the latter is moved from the position shown in full linesin Fig. 4 into the position shown in dotted lines in said figure, thuscausing the weighted end of the lever 49 to be drawn down and causingthe free end of said lever to pull upward upon the rod 48, which in turnlifts the detent or locking device 38 and permits the slide-rod 35 andbelt-shifter to be drawn backwardly by the spring 37. The belt-shifteris thus released automatically when a coin is inserted in the machine,and the locking-pin 41 upon the tight pulley is released at the sametime.

The coin-receptacle 56 here shown consists of a trough 56 of sufficientdepth and width to hold a coin edgewise upon the coin-lever, and thecoin is retained inposition when the lever is tilted by a wire 60,pivotally connected to the'under side of the coin-lever and 1 having afinger 61 extending across the rear open end of the coin-receptacle.This coinretainer has an arm 62 projecting laterally therefrom into thepath of a tripping-pin 63,

secured to one of the spokes of the tight pulley. Soon after the tightpulley is started .into operation the pin 63 engages the arm 62 andtilts the coinretainer, so that its arm 61 will move out of the pathofthe coin and release the latter. The coin-lever' 54 then falls into itsnormal position.

The operation is as follows: When a coin is inserted into thecoin-chute, the coinlever tilts under the weight of the coin, thusreleasing the counterbalanced lever 49 and permitting the longer orweighted arm of the latter to move downward and throw the tappet-leverup into position to be engaged by the rotating tappet 31. Thetappet-lever is then moved by the tappet, causing the counterbalancedlever 49 to rock, and thereby move the detent or locking device 38 outof engagement with the shoulder on the sliderod 35. The belt-shifter isthen moved b the spring 37 into position to shift the be t onto thetight pulley and the tight pulley is simultaneously unlocked by therearward movement of the bracket '40. The tight pul- I ley then startsinto operation, causing the operating-shaft 2 and the feeding andcutting mechanism to be actuated, as hereinbefore described. Shortlyafter the tight pul ley has started into operation the coin-retainer isengaged by the pin 63 and the coin is released from the coin-lever,allowing the latter to fall back onto the light arm of the lever 49. Thecam or shoulder 43 is then engaged by the pin 41 on the tight pulley andthe bracket 40 and slide 35 are drawn back to their normal positions,allowing the locking device 38 to fall in behind the shoulder 36. Thisoccurs during the first half of the revolution of the wheel. The beltthen starts to shift back again onto the loose pulley. Dur- &
